All LIFAN generators are made with Horizontal Shaft OHV engines which feature Industrial duty upgrades like cast iron sleeves, automotive grade rods, pistons, rings, crankshafts, valve and valve springs.

Rated 4.3 out of 5 by 14 reviewers.
Rated 4.0 out of 5.0 by Quiet little generator Got this generator to charge a PV battery bank, it is very quiet and I have had no issues and its been in service for 4 weeks now. My only issue was the cosmetic damage to the generator that was apparently done before it even went in the crate. Based on the time its been in service I would buy another Lifan generator. The spec sheets show it to be a 30 amp max generator but in reality and on the Lifan power website its max is 26.7 amps, that was ok for my use but could be a deal breaker for another use.

Rated 5.0 out of 5.0 by Appears to be a great product at a great price I bought this generator for back up power in the event of a hurricane or just a normal power outage. In testing it , it started up on the second pull. I got the electric start but won't buy the battery because I don't expect to be using the generator that often. It is very quiet... could barely hear it inside my house. I had it on my deck about 20 feet from my house. It handled all my lights, tv, refrig, microwave and a small window a.c. unit. it will handle my oven and range but only if I turn off the other load. it would not run my central a.c. unit and i didn't even try for fear of damaging the generator. I ran it for 45 minutes so time will tell now it runs in the future but it appears to be made very well. The instructions for installing the wheel kit were a joke. The company had designed a much better wheel kit but didn't redo the instructions so have someone with some mechanical skills handy. I contacted their customer service and they were really helpful.

Rated 4.0 out of 5.0 by the product was what i expected The product arrived when I was told it would and the tracking was great. It arrived in good condition with everything included. I was disappointed with the instructions because they were for an older version and were about as clear as mud. After I got it assembled and got a battery ( the one recommended) the wire lead for the positive side was too short to reach the terminal. I had to bend the terminal at the starter for it to reach. I am satisfied with the unit but recommend they spend a little money and update the instructions. October 11, 2013
Rated 4.0 out of 5.0 by Good product for the money Have only had it for a short time but it seems to have good features for the price. Fairly quiet (four stroke engine) and very portable with the wheel kit. Negatives are the assembly manual- the unit had changed since the manual was written, but it was fairly simple to figure things out. Be aware that the electric start model does not come with the battery which costs another $30-40 dollars. July 15, 2013
Rated 3.0 out of 5.0 by nice little generator, a little shy on power. At the time I ordered this generator I had to choose between power and convenience. I am almost 67 years old and my shoulders can't take a lot of pull starting now so I chose the electric start. There is only one 220 outlet and one 120 volt outlet and you have to choose which one to use. My old generator had 2 220 outlets and 4 110 volt ones and all could be used at the same time. It was only one horsepower larger. We used it at my son's house a week ago and it had problems keeping up. He had to choose one appliance at a time to run with a sump pump. I'd recommend it for someone who doesn't have a lot of things to operate. I do love the electric start. March 18, 2014
Rated 4.0 out of 5.0 by Instruction book bad Have not had a chance to use it yet but at this time I feel it will be fine. The instruction book was very bad. Good thing I am mechanically inclined or it might not get put together right. Oh. battery is not included but they have an MSDS to download which led me to believe it had one. June 25, 2013
Rated 5.0 out of 5.0 by Good product; works well; worth the price. The generator works extremely well and is easy to set up and use. Also,the out-put was exactly as claimed in the sales literature and fully satisfies my emergency electrical needs. The only difficulty was the instructions for assembly were not appropriate for the model I purchased and it took a little time to figure out what fasteners to use on each component. Other past reviewers have made this same negative comment and I was surprised LIFAN hadn't made the needed changes to their instructions. April 15, 2014
Rated 4.0 out of 5.0 by easy starting, runs well instructions are poor, product has been updated. some assembly is poor. it works, bottom was bent up a little when received. an attempt was made to pack it securely via an overpack with Styrofoam peanuts. don't pick up on Saturdays from the store. unneeded hardware included because of updates, get threadlocker for what you assemble.
